3DS PicHaxx+slotTool guide

This guide will bring a console from stock to boot9strap using PicHaxx to gain Homebrew Launcher access, and then using slotTool to inject an exploited WiFi profile. Once the exploited WiFi profile has been injected, you will use Safe Mode (a recovery feature present on all 3DS consoles) to activate it.

Before you start

You should only be following this page if:

• Your DSiWare Management menu is inaccessible after improperly uninstalling CFW (it crashes almost immediately when you try to open it)
• Your left and right shoulder buttons work
• You have your movable.sed file, or can easily obtain it

What you need

• The free eShop game "Pokémon Picross"
• Your movable.sed file from completing Seedminer
• The otherapp payload corresponding to your device type, region, and version
  • If your current version is 11.14.0-46, select 11.13.0-45 in the dropdown menu
• The latest release of Luma3DS
• The latest release of unSAFE_MODE

Section I - Prep Work

1. Copy boot.firm and boot.3dsx from the Luma3DS .zip (Luma3DSv10.2.1.zip) to the root of your SD card
   • The root of the SD card refers to the initial directory on your SD card where you can see the Nintendo 3DS folder, but are not inside of it
2. Copy the otherapp payload to the root of your SD card and rename it to otherapp.bin
   • If you do not see the .bin extension, do not add it to the end of the filename
3. Create a folder named 3ds on the root of your SD card if it does not already exist
4. Copy the slotTool folder from the unSAFE_MODE .zip (RELEASE_v1.1.zip) to the 3ds folder
5. Copy usm.bin from the unSAFE_MODE .zip to the root of your SD card

Section II - PicHaxx

1. Open the PicHaxx Save Tool website on your computer/mobile device
2. Select your movable.sed file
3. Select "Build and Download"
4. Wait for the process to complete
   • You should receive a file named 00000001.sav
5. Navigate to Nintendo 3DS -> <ID0> -> <ID1> -> title -> 00040000 -> 0017c100 -> data on your SD card
   • This <ID0> will be the same one that you used in Seedminer
   • This <ID1> folder will be another 32 letter/number folder inside the <ID0> folder
6. Copy the downloaded 00000001.sav file to the data folder on your SD card
   • Overwrite the old save file when prompted
7. Reinsert your SD card into your device

Section III - slotTool

1. Power on your device
2. Launch "Pokémon Picross"
3. After a few seconds, you should see the Homebrew Launcher
   • If you get a yellow screen, force power off the console, then try again
   • If you get any other colour of screen, the game launches normally, or the game crashes, ensure that your otherapp payload is correct and that you have copied all files (boot.3dsx, 00000001.sav) to the correct locations
4. Launch slotTool v1.4 from the list of homebrew
   • If you get stuck on a red screen, forcefully power off the console by holding the power button for fifteen seconds, then retry this section
5. Select the "INSTALL exploit to wifi slots 1,2,3 & shutdown" option
   • You will see some on-screen text and then your system will shutdown
   • If the on-screen text says FAIL, verify that the /3ds/slotTool/ directory has both slotTool.3dsx and slotTool.xml

Section IV - unSAFE_MODE

1. With your system still powered off, hold the following buttons: (Left Shoulder) + (Right Shoulder) + (D-Pad Up) + (A), then press (Power)
   • Keep holding the buttons until your console boots into Safe Mode
2. Press "OK" to accept the update
   • There is no update. This is part of the exploit
3. Press "I accept" to accept the terms and conditions
4. The update will eventually fail, with error code 003-1099. This is intended behaviour
   • If the update does not fail, verify that all three of your internet connection settings have been replaced with Haxxxxxxxxxx, then try again
     
     
5. When asked "Would you like to configure Internet settings?", select "Yes"
6. On the following menu, navigate to Connection 1 -> Change Settings -> Next Page (right arrow) -> Proxy Settings -> Detailed Setup (visual aid)
7. Once you see B9S install SUCCESS on the top screen, press any button to reboot to Luma Configuration
   • If you are stuck on the B9S install SUCCESS screen, it is safe to forcefully turn off the console by holding the power button for 15 seconds
   • If you do not see the B9S install SUCCESS screen, ensure that usm.bin is on the root of the SD card, then try again

Section V - Configuring Luma3DS

1. Your device should automatically show the Luma Configuration menu
   • If you do not see the Luma Configuration menu, turn off the console and hold SELECT while turning on the console to access it
   • If the power light turns on and off, ensure that boot.firm is on the root of the SD card
2. Use the (A) button and the D-Pad to turn on the following:
   • "Show NAND or user string in System Settings"
   • (x) indicates that the option has been turned on
3. Press (Start) to save and reboot
   • Your device should load the Home Menu after a short delay

Section VI - Restoring WiFi Configuration Profiles

1. Launch the Download Play application
2. Wait until you see the two buttons
   • Do not select either of the options
3. Press (Left Shoulder) + (D-Pad Down) + (Select) at the same time to open the Rosalina menu
4. Select "Miscellaneous options"
5. Select "Switch the hb. title to the current app."
6. Press (B) to continue
7. Press (B) to return to the Rosalina main menu
8. Press (B) to exit the Rosalina menu
9. Press (Home), then close Download Play
10. Launch the Download Play application
11. Your device should load the Homebrew Launcher
12. Launch slotTool from the list of homebrew
13. Select "RESTORE original wifi slots 1,2,3"
14. Your device will reboot
